Definitions

  • a heating device 8 in the form of a heating element is arranged on the bottom of the storage container 5 and extends almost over the entire length of the storage container.
  • a cooling unit could also be immersed in the liquid 3 in the storage container.
  • the heating device 8, like the submersible pump 19 or its motor 20, is also fastened under the trough 4, so that the entire unit can be lifted out of the reservoir 5 when the fastening screw 21 is loosened.
  • the scooping level of the submersible pump 19 is slightly above the level of the heating device 8, so that the heating element always remains covered with liquid even when there is an insufficient amount of liquid. Too low a liquid level is indicated by a gurgling pump noise and strong steam generation.
  • a thermostat can also be provided as protection against overheating.
